Wind-resistant beam string structure with high durability and construction method thereof
The invention discloses a wind-resistant beam string structure with high durability and a construction method thereof, and belongs to the technical field of beam string structures. The beam string structure comprises a rigid beam, a tensioning node, a steel strand, a supporting rod and an assembling hole channel; the tensioning node is arranged on the rigid beam; the two ends of the steel strand are connected with the tensioning joints correspondingly. The assembling hole channel sleeves the steel strand, slurry is arranged in the assembling hole channel, and the two ends of the assembling hole channel are flexibly connected with the tensioning nodes; the two ends of the supporting rod are connected with the rigid beam and the assembling hole channel respectively. The steel strand is sleeved with the assembly hole channel, the steel strand is protected, the influence of high temperature, humidity and other climates on the strength of the steel strand is avoided, the durability is improved, and a tension component does not need to be replaced within the designed service life; grouting is conducted in the assembling hole channels, the steel strands are wrapped with cement, the fireproof problem of the structure is solved, and the fireproof time is greatly prolonged; meanwhile, the self weight of the structure is increased through cement, it is effectively guaranteed that the structure does not quit work through prestress under the wind suction effect, and the wind resistance is improved.
本发明公开了一种具有高耐用性的抗风张弦梁结构及其施工方法，属于张弦梁结构技术领域，张弦梁结构包括刚性梁、张拉节点、钢绞线、撑杆和组装孔道；张拉节点设置在刚性梁上；钢绞线两端分别与张拉节点连接；组装孔道套设在钢绞线上，其内部设置浆料，两端与张拉节点柔性连接；撑杆的两端分别与刚性梁、组装孔道连接。本发明在钢绞线外部套设组装孔道，对钢绞线进行保护，避免高温、潮湿等气候对钢绞线强度的影响，提升耐久性能，在设计使用年限内无需更换受拉构件；在组装孔道内灌浆，利用水泥将钢绞线包裹，解决了结构的防火问题，耐火时间大大延长；同时，水泥增加了结构自重，有效保证结构在风吸力作用下预应力不退出工作，提升抗风性能。
